Objective To investigate the clinical effect of sitagliptin combined with metformin in the treatment of sulfonylurea-deficient elderly patients with diabetes mellitus.Methods Sixty patients with diabetes mellitus were enrolled in our hospital from January 2013 to December 2016.The patients were divided into observation group(30 cases) and control group(30 cases) according to the random number method.The patients in the observation group were treated with sitagliptin and metformin.The patients in the control group were treated with gemcitabine, and the clinical treatment effect, fasting blood glucose, postprandial blood glucose, glycosylated hemoglobin, fasting C peptide and postprandial 2hC peptide Level of statistical comparison.Results The clinical effect of the observation group was significantly higher than that of the control group.Before and after treatment, the fasting blood glucose, 2h postprandial blood glucose, glycosylated hemoglobin, fasting C peptide and postprandial 2hC peptide level were not significantly different After fasting blood glucose, 2h postprandial blood glucose and glycosylated hemoglobin levels were significantly lower than before treatment, after treatment of fasting C peptide and postprandial 2hC peptide levels were significantly higher than before treatment.Conclusion The clinical efficacy of serotretine combined with metformin in the treatment of elderly patients with diabetes mellitus is similar to that of Yuxing, and the combination is more convenient and more suitable for clinical treatment.It is worthy to be popularized and applied in clinical practice.

Objective: Hitherto there has been no report on the changes of microvessels and the expression of angiogenic factors after photodynamic therapy(PDT) of liver carcinoma.The purpose of this study was to investigate the effect of PDT on the microvessels and the expression of vascular endothelial growth factors(VEGF) in tumor cells. Methods: The mice models subcutaneously transplanted with Heps liver carcinoma were randomly divided into a PDT group(n= 28) and a control group(n= 28).The dynamic changes of the microvessels and VEGF expression in the tumor cells were observed at 2,6,24 and 72 h after PDT by H-E and immunohistochemical staining.Results: Progressive changes were seen in the tumor microvessels at the four time points after PDT,including dilatation,blood stasis,hypostasis,hemorrhage,and angiolysis.Compared with the control group,the microvessel density of the tumors was reduced significantly(P

Objective To find out the clinical outcomes of twin-twin transfusion syndrome (TTTS) after aminioreduction. Methods Twenty-nine pregnancies with TTTS delivered in Beijing Gynecological and Obstetric Hospital from Nov. 1, 2002 to Sept. 30, 2007 were recruited. The effect of gestational age at the onset, the degree of TTTS and amnioreduction therapy on the fetal outcomes were compared. Results All of the 8 cases with the onset of TTTS before 26 weeks without treat- ment were lost, but 4 out of the 6 with the onset after 26 weeks survived (P=0. 015). Among the 9 cases received amnioreduction, 4 out of the 5 with onset before 26 weeks survived, and significant difference was found compared to those untreated ones (P= 0. 007), but no difference was shown when compared with those developed after 26 weeks(4/4)(P= 1. 000). The average delivery weeks in the untreated ones was earlier than those received treatment E(28.7±4.7)weeks vs (33.2±4.9) weeks, P=0. 001]. Amnioreduction improved the umbilical cord blood flow. For severe TTTS(stage Ⅲ～Ⅳ) with the onset before 26 weeks, the survival rate after amnioreduction was significantly high- er than those untreated ones[4/5 vs 0/5, P=0. 048)]. Conclusions Aminioreduetion is effective in improving the cord blood flow, prolonging the pregnancies, and achieving a higher fetal survival rate.

OBJECTIVE: To observe monocyte chemoattractant protein 1 (MCP-1) changes in ischemic tissue during the process of angiogenesis induction in ischemic limbs by autologous mesenchymal stem cell (MSC) transplantation.METHODS: Twenty male Sprague-Dawley rats were randomized to 2 groups (n = 10): model and MSC transplantation. Femoral and tibial bone marrow was taken to isolate and culture MSCs by percoll density gradient method. Cells of the 3~(rd) or 4~(th) passage were used for transplantation. Severe bilateral hind limb ischemia was surgically created in each group rats. Two hours after model establishment, MSCs (1×10~(11)/L) were infused into the ischemic region of rats from the MSC transplantation group, and the model group received the same amount of phosphate buffered saline. Collateral artery formation was determined by angiographic analysis and histological assessment. CD68~+ macrophage infiltration was examined by immunohistochemistry. MCP-1 protein expression in the plasma and ischemic tissue was detected by enzyme-linked immunosorbent assay. MCP-1 mRNA expression in ischemic tissue was detected by reverse transcription-polymerase chain reaction.RESULTS: At postoperative 28 days, treatment with MSC transplantation lead to collateral vessel formation, and immunohistochemistry demonstrated that CD68~+ macrophage infiltration was lower compared with the model group. MCP-1 protein and mRNA expression in the plasma and ischemia tissue was significantly lower in the MSC transplantation group than in the model group (P < 0.05).CONCLUSION: Following MSC transplantation, MCP-1 may play an important role in ischemia-induced angiogenesis. This indicates that MCP-1 would become one possible target molecule for modulating inflammatory angiogenesis by MSC Transplantation.

ObjectiveTo explore the application of enlargement of plastic surgery for dural closure with radial neuro-patch in standardize large decompressive craniectomy (SLDC).MethodsTwenty-one patients (observation group) who needed a SLDC for various reasons were treated with radial incision in dura to release the high intracranial pressure and enlargement of plastic surgery for dural closure with radial neuropatch from March 2009 to June 2010.The neuro-patch were used as the dural substitutes.Twenty-one patients were treated with SLDC only for the similar reasons (control group).General healing effects were compared betweentwo groups.ResultsIn 6 hours and 72 hours after surgery,the rate of obvious effectiveness in observation group was significantly higher than that in control group [33.33％(7/21 ) vs.14.29％(3/21 ),33.33％(7/21 ) vs.19.05％(4/21 ) 、61.90％( 13/21 ) vs.28.57％(6/21 ),61.90％( 13/21 ) vs.38.10％(8/21 )](P ＜ 0.05).The rate of intracranial infection,cerebrospinal leak and epilepsy in observation group [0,0,4.76％ ( 1/21 )]was significantly lower than that in control group [14.29％ (3/21),14.29％ (3/21),19.05％ (4/21)](P ＜0.05).The rate of subcutaneous or subdural cerebrospinal fluid accumulation,cenencephalocele,cerebral ventricular malformation,brain hernia through the skull window had no significant difference between two groups [19.05％(4/21 ),0,4.76％( 1/21 ),0 in observation group;23.81％(5/21 ),9.52％(2/21 ),9.52％(2/21 ),4.76％( 1/21 ) in control group) (P ＞ 0.05 ).After followed up of 6-12 months,the rate of the well general outcome in observation group was significantly better than that in control group [85.71％ ( 18/21 ) vs.71.43％ ( 15/21 )](P ＜ 0.05 ).The rate of moderate-critical function handicapped in control group was significantly higher than that in observation group [23.81％(5/21 ) vs.9.52％(2/21 )](P＜0.05 ).ConclusionsThe SLDC is effective for decreasing the intracranial pressure,and the enlargement of plastic surgery for dural closure with radial neuro-patch can improve the efficiency and decrease the incidence of complicating diseases.This therapy can improve the patients' general quality of survival and is worth to be popularized in clinic.

Objective To determine the change of maternal heart rate during the treatment with ritodrine for threatened premature labor. Methods110 cases of threatened premature labor were chosen. The ritodrine 100mg in 5% G. S 500mL was intravenously administered. The initial dosage was 6 drops/min, and the dose was increased until uterine contractions were inhibited. The treatment lasted for 40 to 48 hours after the uterine contractions were inhibited, then the oral tablets was recommended. If necessary, repeated treatment was given to some patients. The maternal heart rate was recorded in the whole process of treatment and was compared with the dosage administered. The labor time, fetal weight and Apgar′s score were also analyzed. Results The maternal basic heart rate was increased at first and then decreased. The increasing significantly increased( P ＜ 0.01 ) when the uterine contraction was inhibited. , but no difference showed among the groups of different gestational age( P＞0.05 ). The maternal heart rate was increased with the increasing of ritodrine( max. 140/min). labor time was significantly prolonged with the treatment of ritodrine( P＜0.01 ) ,while that of the idiopathic premature labor was prolonged most obviously ( P ＜ 0.05 ). Average fetal weight was (2.42 ± 0.49) kg, and the average Apgar′s score was≥8. Conclusion In the treatment of inhibiting uterine contractions,the increasing of maternal heart rate caused by ritodrine can be used as an indicator of therapeutic effect.
